OBJECTIVE
Induction chemotherapy with Taxotere, cisplatin, and 5-fluororacil (TPF) was mainly used in hypopharyngeal and laryngeal cancer patients for larynx preservation. This study aimed to assess feasibility and toxicity in oral cavity and maxillary sinus cancer patients.
METHODS
Between 2003 and 2008, 21 patients (18 male, three female; mean age 58 years; 15 patients Eastern Cooperative Oncology Group > or =1) suffering from advanced squamous cell cancers of the oral cavity (seven primaries, eight locoregional recurrences) and the maxillary sinus (six patients) were prospectively treated with three cycles of TPF (q3w) and were scheduled to undergo definitive chemoradiation.
RESULTS
Of 21 patients, 15 (71%) could be treated with all three cycles, one patient with two cycles, and five patients with one cycle. Reasons for incomplete treatment were tumor progression, edema, seizure, bad general condition, sepsis, pneumonia (each once). The infections led to two treatment-related deaths (9.5%). Acute grade III/IV side effects were noted maximally in 11 patients (52%). Main toxicities were afebrile leukopenias and neutropenias and stomatitis. Of 15 patients, six and four patients had a clinical complete or partial remission following three cycles (67%); five patients with recurrences had no response. Ten patients underwent a definitive chemoradiation or radiation (47.6%). After a mean observation time of 17 months, nine patients are alive; one of them developed a local recurrence.
CONCLUSIONS
Chemotherapy with TPF is a highly effective treatment with considerable toxicity that needs special expertise which is best assured in a multidisciplinary setting. Pretreated recurrent cancers demonstrated bad response. A target for organ preservation could be the maxillary sinus; due to tumor regression in advanced oral tongue cancer, consecutively, a reduced function has to be encountered.
